Space telescope – Instrument in space to study astronomical objects.
Spectrometers – Used to measure spectral components of light.
Sundial – Device that tells the time of day by the apparent position of the Sun in the sky.
Telescope – Instrument that makes distant objects appear magnified..
The theoretical limit of useful magnification for a telescope is 50 or 60 times the telescope's aperture in inches, or two times the aperture in millimeters.
So, for a 60mm refractor, the maximum useful power is 120x (i.e., 120 times the magnification of the naked eye)..
It depend upon sky conditions and size of telescope,brightness and size of object.
Andromeda galaxy which is 2.5 million light years is visible to naked eye..
Hubble space telescope already have observed objects about 13 billion light years away.
There is no kilometer range for telescopes..
Most refracting telescopes use two main lenses.
The largest lens is called the objective lens, and the smaller lens used for viewing is called the eyepiece lens..
A good telescope is essential for getting started in astronomy, but with so many brands and models available to choose from, it's hard to pinpoint how much a good telescope costs.
A good telescope costs between $300 and $8,000, depending on your needs and level of expertise..
Astronomers study planets, stars, and other celestial bodies.
They use ground-based equipment, such as optical telescopes, and space-based equipment, such as the Hubble Space Telescope.
Some astronomers study distant galaxies and phenomena such as black holes and neutron stars..

By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth.
In astronomy, the Universe is our laboratory.
Astronomy is the study of everything in the universe beyond Earth's atmosphere.
That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars ..
For anyone completely new to astronomy, the first step is to become familiar with the night sky, how it changes through the night and season by season, and how it varies according to the observer's latitude.
A planisphere (or "star wheel"), monthly sky guide, or computer software will help with this..

X-ray telescope launched in 1977
HEAO-1 was an X-ray telescope launched in 1977.HEAO-1 surveyed the sky in the X-ray portion of the electromagnetic spectrum
Providing nearly constant monitoring of X-ray sources near the ecliptic poles and more detailed studies of a number of objects by observations lasting 3–6 hours.It was the first of NASA's three High Energy Astronomy Observatories
1977 aboard an Atlas rocket with a Centaur upper stage
Operated until 9 January 1979.During that time
It scanned the X-ray sky almost three times
